Complete step-by-step answer:

In the given question we have to understand articles. Articles are words that are used before a noun, depending on weather it is definite or indefinite. They are three articles: a, an and the. The article ‘a’ and ‘an’ are used to talk about someone or something whose identity is not known. In this, the article ‘an’ is used if the noun starts with a vowel (a, e, i, o, u) and the article ‘a’ is used if the word starts with a consonant. The article ‘the’ is used when we are talking about someone or something whose identity we clearly know.
In the given question, the speaker is talking about a particular boy in a particular row. The boy’s identity as well as the row number is clearly known. Hence, the article used should be ‘the’ in both the situations. The only option that gives this as an option is option ‘A. The, the’. Hence, option A is the correct answer.

Note: If the noun starts with a vowel but is talking about something in particular, then the article ‘the’ is used instead of ‘an’. E.g. The elephant in that temple is very famous.
